March 2014. A new research video “Energy Harvested Secured Wireless Sensor Node” has been posted on the CESCA Project Videos page. Graduate students Deepak Mane and Krishna Pabbuleti and CESCA Director Patrick Schaumont at Secure Embedded Systems lab designed and developed a prototype for an autonomous, self-powered wireless sensor node, which can harvest energy from ambient sources.
The sensor node consists of an MSP430, a low-power 8-bit microcontroller from TI which runs the signature algorithms and a 2.4GHz RF transceiver for communicating with the central server. The system harvests its energy from a solar panel and stores it in a super-capacitor. Energy harvesting and system power supply are managed by a custom-built IC from Anagear. Energy measurement infrastructure is also integrated in the system which can be used to measure the amount of energy consumed for computation and communication for different algorithms.
Please check the upcoming CESCA Newsletter for more details about their research and experiment setup.
January 2014. Team Envision is making progress! This student-oriented team has been building an Interactive Vision Assistant “IVA” for visually impaired people to navigate around. The team members are: Preethi Gopalakrishnan, Rubasri Kalidas, Clint Solomon Mathialagan, Pujita Raman, and Adithya Venkatramanan.
The team recently posted a video of their IVA running a dynamic face-recognition algorithm using OpenCV. Check the result at “IVA in action!” at: http://blogs.cornell.edu/cornellcup2014envision/2014/01/17/iva-in-action/#more-10
Support Team Envision by voting for them on the blog survey at: http://www.systemseng.cornell.edu/engineering2/se/intel/news/blogsurvey.cfm (“Team Envision” is listed as the 8th team from the bottom of the page in alphabetical order)
For more information about IVA and Team Envision, please contact Patrick Schaumont, the faculty advisor for the team.

December 2013. Congratulations to the following students who will be graduating in Fall 2013!
November 2013. Five master-level graduate students are one of the 30 selected finalist teams to compete the 2014 Cornell Cup USA, a popular college-level embedded design completion. The 5 students are: Preethi Gopalakrishnan (Computer Engineering), Rubasri Kalidas (Computer Engineering), Clint Solomon Mathialagan (Computer Engineering), Pujita Raman (Electrical Engineering), and Adithya Venkatramanan (Computer Engineering).
The five students, who are assembled under the name Team Envision, intend to implement an Interactive Vision Assistant, a device that supports the blind in navigating, understanding, and interacting with the surroundings. The selected platform for IVA is the Intel DE2i-150 FPGA kit, a platform that combines an ATOM CPU with an Altera FPGA. The team plans to extend this kit with additional sensing capabilities and software to support the objectives of the IVA. The team's academic advisor is Patrick Schaumont, CESCA Director.
The Cornell Cup was created to empower student teams to become the inventors of the newest innovative applications of embedded technology. At the finals scheduled in May 2014 at the Walt Disney World ® Resort, top three finalist entries will be awarded the grand prizes set at $10,000, $5,000, and $2,500.
For more information about how Team Envision is progressing, please contact Patrick Schaumont, the faculty advisor for the team.
October 2013. Hassan Eldib, a Ph.D. Candidate, and his advisor and one of the CESCA faculty members Chao Wang received the 2013 Best paper Award at the Formal Methods in Computer-Aided Design (FMCAD) conference for their paper “An SMT Based Method for Optimizing Arithmetic Computations in Embedded Software Code.”
According to the award announcement, their paper “…tackles a very interesting problem, namely the optimization of control software manipulating fixed-point integer data, and presents an innovative and scalable solution based on the use of SMT solvers and inductive synthesis procedures.” The announcement also mentioned that the paper “…has received strong support in review process.”
Congratulations Hassan and Dr. Wang for the Best Paper award!
September 2013. Dr. Leyla Nazhandali, one of the CESCA faculty members, has been recognized as Teacher of the Week by the Virginia Tech The Center for Instructional Development and Educational Research (CIDER). She was recognized for her innovative teaching methods that stimulate active participation from students, and for original outreach to attract high school students to the computer engineering curriculum.
Congratulations, Dr. Nazhandali !
August 2013. CESCA Faculty member Jung-Min "Jerry" Park and CESCA Director Patrick Schaumont were recently awarded for a new 4-year grant from the National Science Foundation (NSF) to enable novel security technology for shared communication spectrum superhighways. A main goal is to make trustworthy spectrum sharing technically and economically viable. Park is the PI for this collaborative project with two other professors from the economics field.
May 2013. The following students have graduated in Spring 2013.
May 2013. The following students will take an internship during Summer 2013.
May 2013. Dr. Chao Wang, one of the CESCA faculty members, was featured on the Virginia Tech College of Engineering website about his award of the Office Naval Research (ONR) Young Investigator Program (YIP) grant. The YIP grant is the most prestigious one by ONR for faculty members early in their career. The grant is to develop methods and software tools that can detect security vulnerabilities in concurrent software that runs on a modern multi-core computer.
April 2013. Dr. Yaling Yang, one of the CESCA faculty members, has been recognized as Scholar of the Week by the Virginia Tech Office of the Vice President for Research. She was recognized for her work with wireless network modeling, design, and security.
Please read more descriptions about her accomplishments and current projects on her Scholar of the Week page at the Office of the VP of Research site.
Congratulations, Dr. Yang !

March 2013. CESCA hosted its first “CESCA Research Day”, research symposium on Embedded Security at the Virginia Tech Research Center in Arlington on March 15, 2013. Approximately 25 designers and managers from industry, government organizations, academia, and research labs attended the full-day symposium to learn about leading-edge research and development related to secure and embedded systems and to network with faculty, students and other professionals who have similar interests.
CESCA Director Patrick Schaumont welcomed the attendees, followed by Charles Clancy, associate professor and director of the Hume Center, who talked about research directions in security. Three morning research sessions covered the topics of secure design, applications, and secure design methods. Brief overview of the research work was presented by all 7 CESCA faculty members: Professor Michael Hsiao; Associate Professors Lynn Abbott, Leyla Nazhandali, Patrick Schaumont, Jerry Park, and Yaling Yang; and Assistant Professor Chao Wang. Between the research sessions, 8 Ph.D. students from CESCA (Aydin Aysu, Avinash Desai, Zhenhe Pan, Sarvesh Prabhu, Meeta Srivastav, Ting Wang, Lu Zhang) presented their work through poster and demonstration sessions.
After lunch, attending companies introduced themselves to the students for internship and employment opportunities. Because all sessions were also simulcast to Blacksburg, CESCA students in Blacksburg were able to follow those presentations. Participants were then offered 4 parallel tutorial sessions from which to choose: Introduction to Side Channel Analysis; Software Testing and Verification; Physically Unclonable Functions; and Wireless Security.
The website of the Research Day hosts videos as well as slides of the presentations. With this outreach event, CESCA has forged valuable relationships with the participants. CESCA is especially interested into attracting partners to its Industry Affiliate Program, and encourages companies with a stake in critical embedded systems design to contact us.
